Picture a foreman handed money to buy feed for the herd, then using it to cover some other bill instead. The money was never really his to spend. In tax law, a trust fund recovery penalty is the IRS's way of collecting payroll taxes that an employer withheld from workers' wages but did not turn over to the government.

Under Internal Revenue Code § 6672, the IRS can assess this penalty against any "responsible person" who had control over paying the business's taxes and willfully failed to collect, account for, or pay them. That can include an owner, officer, bookkeeper, payroll manager, or anyone with enough authority over company finances. The penalty usually equals the unpaid withheld federal income tax plus the employees' share of Social Security and Medicare taxes - not the employer's matching share.

Practically, this matters because the debt can follow a person, not just the company. The IRS may file a tax lien, levy bank accounts, garnish wages, or intercept funds that might otherwise go toward resolving other debts.

It can also affect an injury claim. If someone expecting settlement money or business revenue is assessed this penalty, the IRS may try to reach those funds through a levy or lien. In disputes, much often turns on whether the person was truly responsible and whether the failure was actually willful.
